Current Postdoctoral Scholar:
Dr. Timothy Hahn received his Ph.D. at Washington University in St. Louis in 2019. His Ph.D. research emphasized comparative planetology among differentiated bodies, including the Moon and Vesta, through photometric investigation of planetary surfaces and sample analysis of representative achondrites (i.e., lunar and HED meteorites). Specifically, his research focused on exploiting “big data” in geological and planetary science through a combination of 1) statistical analysis of compositional data; 2) high performance computing and numerical modeling; and 3) geostatistical analysis of spacecraft-derived datasets. His current research at ASU focuses on using nominally anhydrous minerals (e.g., olivine, pyroxene, and plagioclase) as probes into primordial volatiles in the early Solar System through investigation of achondrite parent body crusts and mantles. Timothy’s research utilizes the Cameca NanoSIMS 50L and Cameca IMS 6f SIMS at ASU. His research will also work to develop high-quality ion implant standards for measuring volatile concentrations and D/H in nominally anhydrous minerals.
Current Undergraduate Students:
Thomas Redford – He is senior with a major in Math. His interests lie in understanding the formation of organic materials in stellar environments and in meteorites. Outside of research, he loves to play chess.
Lucas Reynoso – He is a junior studying Aerospace Engineering and minoring in Sustainability. He is in the Honors College and a National Hispanic Merit Scholar. His interests lie in studying the salts found on the dwarf planet, Ceres, and developing the methodology to prepare salts for NanoSIMS analysis without sample degradation. He also is an avid cyclist and pianist and can be found making beats in his free time.
Jonas Hallstrom – He is a senior majoring in Physics. He is also a member of Barrett, the Honors College and a National Merit Scholar. He is interested in programming applications in physics and math, and in materials of all kinds, including extraterrestrial materials. He enjoys singing, board games, and cats.
Matthew Bryce Rombaoa – He is a junior at Barrett majoring in Biochemistry and minoring in Psychology. He is working with postdoctoral scholar Timothy Hahn to develop a model that examines nebular ingassing during planetary accretion. In his free time, he enjoys playing basketball, volleyball, and guitar.
Tarisa Ross – Tarisa is from Tacoma, Washington State. She received her Bachelors in physics from Howard University, and is currently working on a Master of Earth Science from North Carolina Central University. She likes to collect gemstones, cook, watch anime, stargaze and grow plants. She is also in the process of re-learning how to play the flute. Tarisa is a 2021 Simons-NSBP scholar and will work with Dr. Bose on carbon and phosphorus in micrometorites.
Donovan Gapinski – He is a junior at Barrett Honors College, majoring in Physics. His interests lie in stellar astrophysics and will work on stardust from core-collapse supernovae. Outside of research, his interests include reading, board and video games, and learning dead languages.
Current Graduate Students (associated with CIA since 2017):
Zebadiah Teichert – He is a PhD student in SESE. His interest is in using lithium and boron to trace the thermal history of terrestrial kerogen and shales to understand oil production.
Tyler Quigley – He is a PhD student in the School of Life Sciences. He is interested in understanding the dynamics of molecular transport across the blood-brain barrier of the honeybee worker.
Jonathan Zaloumis – His PhD research is to understand preserved microbial fossils in deep drill cores of serpentine from Oman and Atacama rocks that has strong implications for the sampling strategy for the upcoming Mars rover.
Ashley Herbst – She is a PhD candidate and doing her second project on the production of heavy and rare element isotopes in supernovae.
Qian Yuan – He is a PhD student in SESE and is studying lithium-isotope fractionation recorded in multiple episodes of humites during carbonate metasomatism.
Past Postdoctoral Scholar:
Dr. Ziliang Jin received his Ph.D. at the China University of Geosciences, Beijing. He also worked as a guest scientist in the GeoForschung Zentrum (GFZ) 1280HR SIMS lab in Potsdam, Germany. His postdoctoral research work at ASU focused on the study of water and hydrogen isotopic compositions in anhydrous minerals from the asteroid Itokawa and ordinary chondrites using the NanoSIMS 50L.
